Cleaning instructions
Your UDPi integral suppressors was designed to require minimal cleaning. The 17-4 stainless steel core is welded into one contiguous sealed unit. From the factory your core is pinned and welded to the barrel. 

Recommend cleaning intervals:

After 500 rds:

  1. Clean chamber, barrel, and inside of suppressor tube with a cleaner that will break down carbon and lead deposits.
  2. You can use a wire brush on the inside of the tube if needed. Use caution when soaking outer suppressor tube in concentrated cleaning solution, as damage to the Cerakote finish can occur.

After 2500 rounds:

  1. Remove complete barrel and suppressor unit from firearm, remove end cap, sleeve, and O-ring on back cap.
  2. Place in ultrasonic cleaner with a light degreaser solution (If an ultrasonic is not available then a container larger enough to allow full submersion of the entire barrel and suppressor unit).
  3. Allow to soak for 2-4 hours, use a wire brush to break up and carbon that has build up around the blast chamber ports and on the barrel itself.
  4. Perform same operations on the inside of the outer sleeve.
  5. Check O-ring for damage and replace if necessary (extras are included).
  6. Completely drain all liquid from barrel and suppressors core.
  7. Use Air nozzle to dry all parts.
  8. Re-assemble in reverse order of disassembly.
  9. Re-install barrel assembly and be mindful of your handguard mounting nut orientation and location so your handguard fits and aligns with your receiver.
